Hi, Description: Use msleep() instead of schedule_timeout() to guarantee the task delays as expected. Also uses the set_current_state() macro instead of direct assignment in a pair of spots. I am still concerned about those sleeps, as TASK_INTERRUPTIBLE() is used without any checking for signals. Hence I used msleep() for the longer delay. Perhaps the 30 jiffy delay has not been updated for the larger HZ values and thus could be changed to msleep(300). Signed-off-by: Nishanth Aravamudan <redacted>
